Hey @MarkW ,
currently it looks like that with the zammad api it is not possible, since it only uses the user language for the locales it gathers:
I also checked my addon Rolfs-TableSearch, but with that you would need multiple REST requests to climb up to the tables and find the proper locales which will get inconvienient as well, since you only have postgres search.
Your best chance is maybe to access your elastic search server directly and query it manually without zammad between? Then you would have the pro’s of a nice search and could grab single data via official api.
Would this maybe an option?
